Just a wild guess, but maybe he had some sort of growth plate injury at some point, or it could be a hereditary or congenital defect that is only now coming into play since his legs are now quite long. A 3% discrepancy in length isn't very noticeable on legs that are only 10" long, but on longer legs would be more noticeable.
There are surgeries that can be done to correct leg length discrepancies if it proves to be a permanent issue, but if it doesn't cause him pain and isn't likely to cause long term mechanical issues and increased risk of arthritis/injury, I'm not sure I personally would pursue it. If it is likely to cause any issues long term, that might change things, particularly since he's a young dog. It may be worth at least a consultation with an orthopedic vet, just to know your options.
